Equip only to Jinzo. While this card is equipped, the equipped monster's effect does not negate the effects of its controller's Trap Cards. When this card is removed from the field, destroy the equipped monster. This card's activation and effect cannot be negated.
- Note that Amplifier's activation and effect cannot be negated. This is written on the card.
- It is the controller of Jinzo equipped with Amplifier, not the controller of Amplifier, that can activate Trap Cards.
- If you equip Amplifier to your opponent's Jinzo, then your opponent can activate Trap Cards and they will not be negated.
- If you control 2 Jinzos and only 1 is equipped with Amplifier, you cannot activate Trap Cards.
- If you have Jinzo with Amplifier, your Trap Cards are not negated and their effects are applied, including Aqua Chorus, Royal Command, Royal Oppression, Coffin Seller, Forced Requisition, Mirror Wall, Gravity Bind, Rivalry of Warlords, Minor Goblin Official, Final Attack Orders, Pitch Black Power Stone, Bad Reaction to Simochi, Skull Invitation, Skull Lair, The Eye of Truth, Spirit Invitation, Respect Play, Ring of Destruction, Metalmorph, Torrential Tribute, Self-Destruct Button, Zero Gravity, and Big Burn.
- If you activate Mask of Restrict and you have Jinzo with Amplifier, Mask of Restrict is not negated and its effect still applies, so neither player may Tribute.
- If the controller of Jinzo with Amplifier has activated the effects of Regulation of Tribe, Spatial Collapse, Robbin' Goblin, Robbin' Zombie, Curse of Darkness, etc., their effects are not negated, but if the opponent activates them, they ARE negated.
- If your Amplifier is switched from your Jinzo to your opponent's Jinzo with Tailor of the Fickle, then your Jinzo is not destroyed.
